Description
Technical field
The present invention relates to transforaminal approach fusion technical field, espespecially a kind of lumbar fusion cages and its instrument is used.
Background technology
Common lumbar disease causes patient to occur based on disc herniation, lumbar spinal stenosis, Degenerative spondylolishesis
A series of slight illness such as Low Back Pain and lower limb pain numbness, so as to have a strong impact on the work and life of patient.Lumbar spinal fusion is treatment
One of unstable and lumber spondylolisthesis classical way of lower lumbar spine, can recover the physiologic radian of backbone, rebuild lumbar stability, correct
The effective ways of abnormal load mode and alleviation clinical symptoms.Wherein with the fusion rate highest of interbody fusion, curative effect is the most true
Cut.Waist Invasive lumbar fusion device (Cage) is used exclusively for the medical implant of lumbar intervertebral fusion, can play support intervertenral space
Effect, is clinically widely used.
Way of escape interbody fusion (PLIF) is operative approach mode relatively conventional in the prior art, for example,
CN203609549U discloses a kind of lumbar fusion cages suitable for way of escape interbody fusion, and the fusion device body front end is bullet
Head design, its body upper surface and/or body lower surface are provided with the consistent pawl in direction, can prevent fusion device with increasing friction force
Slide.But which surgical procedure is cumbersome, overlong time, cause the amount of bleeding of patient excessively, operating difficulty is larger.
Transforaminal approach fusion (TLIF) is the new interbody fusion for being substantially better than aforesaid way, the operation method
With operating, more easy, wound is small, the features such as reduction bony structure iatrogenic destruction.For example, CN103622767A is disclosed
A kind of fusion device suitable for through intervertebral approach fusion, the fusion device distal end is designed for sub warhead, reduces resistance, implantation side
Just.Its problem for existing is that all unidirectional straight-tooth of tooth form of fusion device side are unfavorable for the knot of fusion device and centrum
Close, in the later stage due to the activity of human body, it may appear that fusion device slip phenomenon.
The content of the invention
It is an object of the invention to provide a kind of lumbar fusion cages and its use instrument, be applied to transforaminal approach fusion
In art, prevent fusion device from coming off, realize the firm combination of fusion device and centrum.
The technical scheme that the present invention is provided is as follows：A kind of lumbar fusion cages, including main body and development needle, wherein, the master
Body is kidney type cavity, and the kidney type cavity includes front end, end, upper surface, lower surface and side,
The upper surface and the lower surface are provided with anti-slop serrations combination, anti-slop serrations combination include the first tooth group,
Second tooth group and arc-shaped gear, wherein, the first tooth group and the second tooth group are the parallel transverse teeth of a row, and institute
The transverse teeth for stating the first tooth group is different from the arrangement angle of the transverse teeth of the second tooth group；The arc-shaped gear is located at described first
The adjacent of tooth group and the second tooth group, and the arc-shaped gear respectively with the transverse teeth and second tooth of the first tooth group
The transverse teeth of group is approximately tangent.
The side is curved surfaces, and the cambered surface of the arc-shaped gear is opposite towards the cambered surface direction with the side.
Change the horizontal toothing that conventional anti-slop serrations are unidirectional arrangement, instead two groups of different transverse teeths of angle and arc
The anti-slop serrations of the mixed form that tooth is collectively constituted, different anti-slop serrations arragement direction greatly enhances the frictional force with centrum,
Enhance anti-slip function.And transverse teeth and the tangent combination of arc-shaped gear also can enlarged surface and centrum contact surface
Product, further increases anti-slip function.
The direction of the arc-shaped gear and the arcuate flanks is conversely, when lumbar fusion cages enter fashionable, comply with the arc of arc-shaped gear
Direction, into rear arc tooth provide inside hold, i.e., when lumbar fusion cages have outwards come off trend when, arc-shaped gear
Larger resistance can be provided prevents it from coming off.
Preferably, screwed hole is provided with the end, is distributed on the side, the upper surface and the lower surface
There are at least two first location holes.When using the lumbar fusion cages using clamping device, only screwed hole and two need to have been fastened
3 points of location hole can complete the fastening of lumbar fusion cages, and convenient to use, fixation is very firm, when can shorten operation
Between, reduce the risk being likely to occur in operation.
Specifically, the first positioning number of perforations is 2, closing at the front end for the side is disposed side by side on.
Specifically, being provided with bone grafting window on the side wall.
Preferably, the development needle is tantalum wire development needle, and the main body is polyether-ether-ketone structure.Good biocompatibility, resists
Radiation, wear-resistant, creep resisting ability is strong.Can be organically combined with human body, stress shielding is small, have positive role to promoting bone fusion.
X-ray can be passed through, artifact will not be produced and blocked, facilitate doctor to assess fusion situation.
The end is arcuate surface, and the front end is bullet-headed surface, the end, the front end and described
Side seamlessly transits linking.
Invention additionally discloses a kind of use instrument of lumbar fusion cages, for the lumbar fusion cages, including holder and
Connecting rod, wherein the holder includes handle portion and handle part, the handle portion is Curved with the handle part joining place
Shape；
The handle portion includes a tapped through hole axially penetrated through with the handle part joining place from the handle portion, institute
State connecting rod and pass the screwed hole that the tapped through hole is anchored on the lumbar fusion cages end, be provided with the handle part and institute
State corresponding second location hole of the first position of positioning hole.
Operation consent, aligns pass through connector with the first location hole of lumbar fusion cages using the second location hole of instrument first
Primary Location, the tapped through hole that connecting rod screws out handle portion is then screwed into the screwed hole locking of lumbar fusion cages end, completes waist
The fastening of vertebra fusion device.
In surgical procedure, lumbar fusion cages are implanted into human body and correct placement by transforaminal.
Post operation, first screws out connecting rod from the screwed hole of lumbar fusion cages end, then by the first location hole and second
Connector on location hole takes out, so as to complete the dismounting of lumbar fusion cages.
The lumbar fusion cages provided by the present invention, can bring following at least one beneficial effect：
1st, the horizontal toothing that conventional anti-slop serrations are unidirectional arrangement is changed, instead two groups of different transverse teeths of angle and arc
The anti-slop serrations of the mixed form that shape tooth is collectively constituted, different anti-slop serrations arragement direction greatly enhances the friction with centrum
Power, enhances anti-slip function.And the transverse teeth combination tangent with arc-shaped gear also can enlarged surface and centrum connect
Contacting surface is accumulated, and further increases anti-slip function.Contribute to bone grafting, be relatively beneficial to fusion.
When the 2nd, using the lumbar fusion cages using clamping device, only screwed hole and two 3 points of location holes need to have been fastened i.e.
The fastening of lumbar fusion cages can be completed, improve operation in fusion device fix speed, it is easy to the carrying out of operation, reduction perform the operation into
The capable time, the blood loss of patient is reduced, great meaning is suffered from for doctor and patient.
